The author states:

This isn't strictly true though is it? It was my understanding even mmap() MAP_ANONYMOUS used a file interface, and that the way the kernel creates anonymous maps is by creating an instance of /dev/zero in tmpfs. Although I believe the file descriptor might be ignored however.

It seems to just pass around a null struct file pointer and special cases that.
